What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While entering a parking space at approximately 5 mph the gas pedal stuck and accelerated causing the car to jump curb and hit a wall causing severe damage to car and driver.The engine was still rerving and had to be shut down after the incident.
I was involved in an auto accident. The front driver side quarter panel was hit. No airbags deployed in either car. Immediately upon the collision, I tried to stop the car, but it accelerated on it's own. The car would not stop.
Oil cooler housing leak same issues with Hyundai/kia class action
The AC system on this car, and seems series of years is widely known to have major issue, as is the case with mine. I'm having issues with the dealer telling me the car is out of warranty 35k miles, 2019 year.
Caused blowout on the interstate that almost caused an accident. Blowout then caused damage to wheel sensor that caused car to loose power steering. Repair cost is estimated a $9000.00 repair.
When I accelerate my car stalls and is sluggish. Also when I accelerate my car stalls and speeds up uncontrollably, which is a concern for safety. I’ve contacted the dealership where this repair was completed and told them all the issues I’ve been having since the repair was completed.
At just 41,000 miles, the oil pressure sensor has failed. There are many on-line reports of this issue going back several years for the Genesis G80 sedan. It appears this is NOT covered under the 10 yr/100,000 mile warranty and is only covered by the 5 yr/60,000 mile warranty.
Oil pressured sensor went bad $2500 fix from dealer. In Korea this is a recall. The Genesis forums are full of complaints regarding same issue. The factory should cover this but the 10 year 100000 mile warranty does not cover it since it is considered an electrical part.
